how to compute the ANTI derivative of 1 / x^3(adsbygoogle = window.adsbygoogle || []).push({});

I think I need the formula: f(x) = 1/x^n than f'(x) = -n/x^n+1 but I'm not sure and don't know how to use it.

I know the answer is: -0.5 * x^-2 but have no idea why.

could someone explain this to me please?
